President Juncker met on 29 April in the margins of the European Council the Prime Ministers of Slovenia and Croatia, Miro Cerar and Andrej Plenković, on the management of flows of persons at the borders between Slovenia and Croatia and they stated the following:
"We had constructive talks in a solution-oriented spirit.
We agree that EU law reinforcing the controls at the Schengen borders and the security of our Union must be applied and implemented. In this context, we welcome the fact that Croatia will have full access to the Schengen Information System by 27 June 2017.
The Commission stands ready to and will assist Slovenia and Croatia in providing effective and non-bureaucratic short and long-term solutions for the implementation of the systematic checks at the borders. Slovenia and Croatia both consider the Commission's technical guidelines as very helpful and as a very good basis for their further cooperation.
Slovenia and Croatia agree that they will notify the Commission – in accordance with the Schengen Borders Code – of the decision to carry out targeted checks whenever the waiting time at specified land border crossing points between the two countries is longer than 15 minutes."
